A method and system for identifying the location of mobile units (20) within a cellular telephone system (10). A subset of cells is dynamically assigned to a mobile unit based upon the cell location of the mobile unit at the time of registration. The mobile unit records the subset information, and as long as the mobile unit remains in one of the cells in the subset, it does not re-register its location with the system. The system is able to locate the mobile unit within the assigned subset of cells. When the mobile unit enters a new cell that is not within the subset of cells, it re-registers with the system which then assigns a new subset of cells corresponding to its location within a new cell that did not belong to the previous subset. |
